Landscape Evolution of the Coastal Zone of Xiangshui-Binhai Port Area of Jiangsu Province and Its Impact on Regional Carbon Storage
Based on the data of the three phases of remote sensing images and the InVEST carbon storage model,the landscape evolution process and the dynamic response of regional carbon storage in the coastal zone of Xiangshui-Binhai Port area were quantitatively analyzed.The results showed that from 1984 to 2020,the farmland and salt pans in the study area were converted into construction land on a large scale,and the salt marshes,tidal flats,unused land and part of the salt pans were mainly converted into aquaculture ponds.As a result,the total amount of regional carbon storage was lost by 222,000 t,and the high-value area of carbon density was directly reduced by 15.7％spatially.The conversion of farmland to construction land is the most important driving factor and contributor to the degradation of carbon storage function in the study area,while the conversion of tidal flats to seawater and tidal flats to aquaculture ponds also bring relatively low carbon storage losses.
